COMBINED ERASER-HOLDER AND POINT-PROTECTOR FOR PENCILS.

Application filed May 9, 1917.

T 0 all whom it may concern Be it known that I, VERNON B. Dawson, acitizen of the United States, residing at Bridgeton, in the county ofCumberland, State of New Jersey, have invented certain new and usefulImprovements in Combined Eraser-Holders and Point-Protectors forPencils; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention is an improvement in pencil attachments and hasparticular reference to a combined eraser holder and point protector.

An object of the invention is to prolong the usefulness of a pencileraser by providing an improved holder therefor, a portion of which isadjustable to uncover or expose the outer or operative end thereof asthe same wears away.

Another object is to provide a device of this character which is simplein construction, easy to manufacture and effective in carrying out thepurpose for which it is desi ned.

he inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which, for the purpose of illustratingthe invention, is shown in the accompanying drawing, wherein:

Figure 1 is a side elevation of the attachment showing the same appliedto a pencil. Fig. 2 is a longitudinal sectional view.

Fig. 3. is a transverse section on the line 3--3 of Fig. 1.

Referring more particularly to the accompanying drawing, the numeral 5indicates a pencil upon either end of which is adapted to be mounted theeraser holding member generally indicated b the numeral 6 and preferablyformed 0 an elongated, open ended tube made of any desired material andhaving one end split as indicated at 7 to provide the resilient lips 8which are adapted to engage over the pencil and tightly grip the same toprevent accidental displacement. Intermediate the ends of the member 6the same is provided with a fixed bead 9 employed to facilitate theadjustment and removal of the member upon and from the pencil. The endof the holding tube 6 opposite that which is split has mounted thereinthe rubber eraser 10 which is preferably Specification of LettersPatent.

made the same shape and cross section as the tube (3 in order that itsinner end may be forced for a short distance into such member to tightlyfit the same. By reason of the present invention it is possible togreatly increase the length of the eraser 10 and thereby prolong theusefulness thereof and avoid the necessity of constantly replacing thesame, as well as obviate having a pencil Without an eraser, as commonlyoccurs, owing to the fact that the eraser usually wears out before thelead.

It will be obvious, from the drawing, that a considerable portion of thelength of the eraser projects beyond the end of the tube 6 in which itis mounted and in order that the projecting part of said eraser may beheld in a comparatively rigid position, use is made of a sleeve 11preferably of the same formation in cross section as the tube 6 and of adiameter slightly greater than the latter so that it will fit upon andfrictionally engage the same and considerable pressure will be necessaryto adjust the sleeve longitudinally. In order to facilitate thisadjustment the sleeve is provided with a fixed bead 12 intermediate itsends which may be engaged by the fingers of the operator to provide asuitable grip. l/Vhen the sleeve 11 is in the position shown in Figs. 1and 2, only a comparatively small portion of the outer or operative endof the eraser 10 projects beyond the outer end of said sleeve so thatthe eraser will be held in a comparatively rigid position, and as theend of the eraser is worn the sleeve ll may be adjusted inwardly uponthe rubber and along the tube 6 until the inner end thereof contacts thefixed bead 9 at which time the eraser will yet pro'ect slightly beyondthe end of said tube 6. 'lhe remaining portion of the eraser may then beextracted and replaced by a new eraser.

It will thus be seen from the foregoing description that the attachmentmay be readily mounted upon either end of a pencil in order that thepoint ma be protected when not in use and that w en the usefulness ofthe eraser is exhausted the attachment need not be thrown away but needonly having another eraser mounted therein and can be used on otherpencils.
